BINDING ATTACHMENT FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 441,297, dated November 25, 1890.

Application filed June 5, 1890. Serial No. 354,372. (No model.)

To all whom it may concern:

Be itknown that I, JOHN G. GILMER, a citizen of the United States, residing at Oxford, in the county of Sumter and State of Florida, have invented a new and useful Binding Attachment for Harvesters, of which the following. is a specification.

This invention has relation to binding attachments for harvesters.

an extremely cheap and simple attachment and one which is adapted for rapidly and efficiently forming the band and applying the same around the gavel.

Various other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the claims.

Like numerals of reference indicate like parts in all the figures.

In constructing my binder attachment I provide two opposite longitudinal side frames 1 and 2. These side frames 1 and 2 will, for convenience, be designated as the gear-side frame 1 and the cradle-side frame 2.

The attachment is designed for use upon any ordinary reaper or mower, and the mechanism herein described for imparting motion to the various parts of the machine is therefore subject to slight changes and modifications necessary to form the train of gearing for operating the elements, and I therefore do The objects of the invention are to provide.

not limit my invention with regard to the details of construction herein set forth.

The side frames 1 and 2 are connected by suitable cross-bars 3, and the side frames 1 are preferably open to lend lightness to the structure.

at designates a pair of inclined bars which form a part of the gear side 1 of the attach= ment, and upon the central upper edges of said bars there is formed a bearing 5, in which is mounted for rotation the power-shaft 6, said shaft being provided outside of its bearings and at one end With a gear 7, engaged and operated by a suitable train of gearing connected with the motive power of the harvester. Between the bearings the shaft is provided with a master-gear 8, which gear has one-half of its circumference left plain or untoothed.

In the upper side bars of the gear-sideframe is mounted a shaft 9 in bearings 10, which shaft beyond its inner bearing carries a gearwheel 11 and between its bearings a small pinion 12, the teeth of the latter being designed to engage the teeth of the master-gear 8. Below the shaft 9 there is journaled in bearings 13 upon the side bars 4 a crank-shaft 14, the crank 15 of which is upon the inner side of the gear-frame. The crank-shaft between its bearings is provided with a small gear 16, and between the crank-arm and the inner bearing said shaft: has mounted loosely thereon a small pinion 17 and a larger gear 18, the gear and pinion being fast to each other, and therefore adapted to rotate together, and the small pinion being engaged by the teeth of the gear-wheel 11.

Projecting from the free end of the crankarm is a tubular shaft 19, provided with a spiral slot 20 extending throughout its length, said shaft projecting laterally or across the frame to a point near the opposite side of said frame.

Mounted loosely and adapted for rotation in the tubular shaft 19 is a tubular spindle 21,provided at its outer end with a conical head 22, through which the bore of the spindle extends. The head and spindle are spirally slotted, as at 23, the slot being disposed in a direction opposite to that of the slot 20 of the shaft 19. The rear end of -the spin dle is connected or made fast to ashort shaft Ioo 24, which passes transversely through the free end of the crank-arm 15, and has mounted thereon a small pinion 25. This comprises the twisting mechanism, and by the operation of the same, as I will now proceed to describe, the band is formed from the gavel.

Motion being imparted to the master-gear, sald gear rotates during one-half of its revolution the shaft 9 through the medium of the p1n1on 12, and also rotates the gear 11. The gear 11 rapidly rotates the small pinion 17 and gear 18, which are loose upon the crankshaft 14. This rotation is imparted to the small pinion 25, which is rapidly revolved by the relative sizes of gears, irrespective of the rotations of the tubular shaft 19. The master-gearS during a portion of its revolution rotates the small pinion 16 and with it the shaft 14 and the crank-arm15, which revolves carrying the laterally-disposed tubular shaft 19, which, it will be observed, travels in a path opposite to the direction of rotation of the tubular spindle.

In bearings 26, located upon the inclined bars 4 in rear of the master-gear, there is 3ournaled a transverse shaft 27, which between the side bars 4 carries a gear 28, a small portion of the surface of which is plain or untoothed and adapted to ride over the plain portion of the gear 8-, by which it is driven during a portion of the revolution of said gear 8. The opposite end of the shaft 27 passes through the cradle-side frame 2, and is mounted in bearings 29, formed in said side frame. A crank-arm 30 is mounted upon the last-mentioned end of the shaft 27, and has pivoted, as at 31, to said arm a link 32. Guides 33 are secured or formed upon the outer side of the side frame 2, and in said guides there is mounted for reciprocation 'a rack-bar 33*, a portion of the surface of which is plain, as at 34, leaving toothed portions 35 in rear thereof and 36 atthe front end thereof. A shaft 37 is journaled in the side frame 2, and at an inclination above the same there is journaled a second shaft 38. Upon the shaft 37, outside of the wall, is mounted a loose pinion 39, which is engaged and operated by the toothed portion of the rack-bar.

40 represents a half-pinion mounted upon the shaft 38 and rigid therewith, said pinion being engaged and driven by the pinion 39. The shaft 37 is a fixed shaft, while the shaft 38 is movable, and within the frame said shaft 38 has fixed thereto a curved arm 41.

The.side frame 2 is provided with a semicircular opening or cradle 42, concentric with the shaft 14 of the opposite frame; and the curved arm 41, which is for ejecting the sheaf,

is concentric with the opening or cradle and adapted to take below the same within the frame. At the opposite side.of the opening or cradle is journaled a shaft 44, which at its outer end carries a small pinion 45, one-half of the periphery of which is plain or un toothed, the teeth of said pinion being engaged by the toothed portion 35 of the rack-bar.

a hook 64.

Between the sections of the frame 2 there is fixed upon the shaft 44 the gathering and binding arm 46 of semicircular shape and adapted to span the cradle to complete the circle formed by the same and the cradle.

In a transverse bar 47 connecting the two side frames 1 and 2 there is stepped a short vertical shaft 48, the upper end of the shaft having bearing in a bearing-bracket 49 secured to the inner side of the frame 2. The shaft 48 is provided at its lower end with a small pinion 50, the teeth of which are engaged by a toothed sector 51 formed at the front end of a pivoted sector-lever 52. A bolt 53 serves as the pivot for said lever, and coiled about the bolt is a convolute spring 54, one end of -.,.which is made fast to the shaft and the other to the lever, so that said lever is actuated or maintained by the spring in a rearwardly-disposed position against the stop 55. The rear end of the lever is provided with an extension or tail 56,'which terminates in the path of a trip-lug 57 formed upon the inner side of the master-gear 8, so that once during a revolution of said master-gear the sector is oscillated against the spring in one direction and by the spring retracted. The upper end of the short vertical shaft 48 carries a crank-arm 57, at the outer end of which is located a bearing-stud 58, which arm, it will be apparent, is oscillated by the sector during every revolution of the mastergear. A bracket 59 projects from the frame 2 opposite the bracket 49, and is provided with a bearing-stud or guide 60.

61 designates an arm longitudinally slotted, as at 62, for the reception of the stud 60, and pivoted near its front end to the bearing-stud 58, for which purpose it is provided with a series of adjusting-holes 63, any one of which is adapted to receive the bearing 58. The front end of the arm terminates in This completes the construction of my attachment, with the exception of a platform 65 mounted upon the side frame 2 and secured to the under side of the upper rail of the side frame '1, so that said upper rail serves the function of an abutment or header for heading up the grain previousto its formation into [the gavel, and upon said platform is delivered in the usual manner the grain from the harvesting mechanism. The grain falls upon the table, the butts .being disposed toward the side frame 1, against which, as before stated, they are headed.

By reason of the gearing specified the gathering and binding arm 46 will be rapidly oscillated from under the platform or table through the same and over the cradle. At each forward movement of the arm all grain upon the table is brought over and deliv' bular spindle is making a number of rapid revolutions. At each revolution of the tubular spindle the conical head thereof takes Within its slot a series of straws, which are engaged and taken into the hollow spindle and by the rapid rotations of the same twisted into a rope or band, which is drawn outas the tubular shaft 19 comparatively slowly revolves around the sheaf. The revolutions of the twisting cone-shaped head continue to add the straw, so that the rope or band iscontinuous until the last quarter of the revolution of the tubular shaft, when, by reason of the peculiar gearing hereinbefore mentioned, said tubular shaft stops and the arm 61 is-thrust forward against the band as its terminal comes from the cone, and after such movement the tubular shaft continues its revolution. In the forward thrust or reciprocation of the arm 61 the hook 6 L at the front end of the same passes underneath the band already drawn around the sheaf and, forcing the terminal of the band under the band, thus fastens and prevents it from coming loose. After forming the connection the masterwheel has passed a sufficient distance to bring its tripping-lug out of contact with the vibrating sector-arm, and the latter is by its spring immediately retracted. When this op-. eration is taking place it will be apparent that the gavel has been transformed into a sheaf, and at this moment the shaft 27 is rotated and through the medium of the crankarm 30 and connecting-rod 32 the rack-bar 33 is moved forward and back again and during its forward movement suddenly elevates the curved ejecting-arm 41 and throws the sheaf from the cradle.

By the term revolving, as applied to the motion given to the part 19, I mean moving in a circular path around an imaginary center, and by the term rotating, as applied to the part 21, I mean turning Within or upon an axle, similar to the movement of a wheel. Thus these commonly synonymous terms are employed in contradistinction to each other.
